Temperature dependent and atmosphere dependent properties of Fe2P phase formation. a XRD pattern of 60 nm LFP after carbon coating in Ar from 700–900 °C. b XRD pattern of 60 nm LFP after carbon coating in Ar/H2 from 600–800 °C. c TEM characterization of Fe2P phase and LFP for 60 nm LFP annealed in Ar/H2 (left side) and Ar (right side) gas at 700 °C. Inset of left picture is the diffraction pattern of Fe2P phase and HRTEM images, inset of right picture is the diffraction pattern of LFP phase and HRTEM images. Scale bar, 500 nm in TEM, 5 nm in HRTEM in the left picture. Scale bar, 200 nm in TEM, 5 nm in HRTEM in the right picture
